Abstract. The article discusses the use of laser treatment to produce surfaces that enhance boiling heat transfer. The laser beam has been applied on copper substrates to generate longitudal fins of regular geometry. The altered morphology pattern enables to dissipate higher heat flux values than the smooth, untreated surface – in the case of distilled water and ethyl alcohol as boiling agents. The issue of modeling nucleate pool boiling heat flux on laser processed surfaces is discussed in the paper considering two selected models of boiling.

Abstract. The article is a case study on the use of selected quality management tools in a company from the automotive industry for the purpose of improving the basic production process carried - the assembly process. Quality tools such as Pareto-Lorenz diagram, Ishikawa diagram, and 5WHY method were used. The analyses carried out with the use of quality tools made it possible to identify non-conformities that most often occurred during the assembly process of the tested products, indicate the causes of these non-conformities, and develop suggestions for improvement. The most frequently found non-compliance of products was the disconnection of an element during assembly, due to damage to materials in the warehouse. The root cause turned out to be the lack of control of the state of materials available in the warehouse according to the control plans in force at the plant. The need to introduce changes in the organization of warehouse work, in particular, to increase supervision over the control of the condition of materials and to introduce 100% control of products manufactured in the plant, was indicated as improvement measures.

Abstract. This work concerns studying the characteristics of a pneumatic cushion in a system for moving heavy loads. Particular emphasis has been placed on the airflow parameters through the main supply nozzle, including the average flow velocity. Critical flow at the speed of sound can occur under certain circumstances. In the subsequent steps, a mathematical model of a pneumatic cushion was formulated, next, a simulation model was built in the Matlab/Simulink system, and then numerical simulations were carried out. As a result, it was estimated whether there is a flow with a safe, appropriately low speed in a given range of load and supply pressure.

Abstract. Thanks to their vast surface area, activated carbons are materials of great interest. They are used as adsorbents for both liquid- and gaseous impurities. To improve their properties, impregnation with different substances is conducted. In this paper, such an impregnation was done using copper(II), manganese(II), silver(I), and zinc(II) salts. The aim was to compare the inner structure of the impregnated activated carbon with a non-impregnated one. It was done by Brunauer-Emmett-Teller (BET) adsorption-desorption isotherms that were plotted and described. Lastly, the pore size and volume were determined by Barrett-Joyner-Halenda (BJH) method. The results show that the presence of zinc(II) salts helped to develop the mesoporous structure of activated carbon and resulted in an increase in the surface area of the sorbents, while silver(I) decreased it.

Abstract. Problems with product quality during negative climate changes make the continuous improvement process difficult. The search for approaches consists of methodical and possible detailed analysis areas of these types of problem types. Therefore, the objective of the article was to develop a method to analyze problems with the quality of products considering the impact on the natural environment. The method was developed by a coherent combination of selected techniques, i.e.: brainstorming (BM), Ishikawa diagram, 5M rule, multiple voting, seven-point Likert scale, and the IPA method. A method was carried out for mechanical seal of the 410 alloy, on which a porosity cluster was detected. The originality of the study is that the proposed method supports a consistent methodical analysis of any problem with the quality of products and verifies these problems in view of their impact on the natural environment. Simultaneously, the result obtained from the method determines the main causes of the problem, from which to begin improving the quality of the product considering the impact on the natural environment. This method can be applied to any product and the incompatibilities detected on them. Therefore, the method can be used in service-production enterprises to improve products in terms of qualitative-environmental.

Abstract. Magnesium alloy ZK60 is a biocompatible and biodegradable material that has gained attention for its potential use in biomedical applications due to its high mechanical strength, lightweight properties, and biocompatibility. However, the high chemical reactivity and poor resistance to corrosion of magnesium alloys limit their use. This study evaluates the results from a potentiodynamic polarization test (PD) on ZK60 with surface treatments of plasma electrolytic oxidation (PEO) and PEO+PVA (Polyvinyl Alcohol with Glycerin). The aim is to understand the impact of these treatments on the corrosion behavior of ZK60 and to improve its properties for medical applications. The results showed that the PEO surface treatment significantly improved the corrosion resistance of ZK60, and the combination of PEO and PVA resulted in further improved corrosion behavior. This study highlights the potential of PEO and PEO+PVA treatments for improving the corrosion resistance of ZK60 and its suitability for use in biomedical applications.

Abstract. This paper aims to study the secondary aluminium alloy AlSi7Mg0.3 with higher Fe content after heat treatment. The addition of Mn is also investigated. The quantitative analysis was performed to evaluate the effect of higher Fe content on the amount and shape of platelet-like Fe-rich intermetallic phases. As a method of corrosion resistance testing an immersion test in 3.5% NaCl was used. This test was done in order to evaluate the influence of higher Fe content and Mn addition in heat-treated AlSi7Mg0.3 alloys. The results show that the Mn addition increases the corrosion resistance of AlSi7Mg0.3 alloys, but not significantly. AlSi7Mg0.3 alloys have numerous uses within the automobile and other sectors.

Abstract. This study analyzed the influence of electrolyte composition on the corrosion resistance of plasma electrolytic oxidation (PEO) coatings on EV31 magnesium alloy. An electrolyte solution was prepared by mixing 12 g/l Na3PO4 and various levels of KOH (1, 2, and 4 g/l). The PEO coating was produced with a direct current (DC) regime of 0.05 mA.cm-2 current density and a maximum voltage of 630 V. Electrochemical impedance spectroscopy was performed to assess the corrosion resistance after one hour exposure in 0.1 M NaCl. The results indicated that KOH content has a substantial effect on the morphology and corrosion resistance of the PEO coating and align with previous similar studies. The lowest porosity and highest polarization resistance were observed in the PEO coating prepared with 2 g/l of KOH in the electrolyte, resulting in the best corrosion resistance among the evaluated samples. The presence of only one capacitive loop in the Nyquist diagram and low polarization resistance Rp values of the samples with 4 g/l of KOH in the electrolyte indicated insufficient compactness due to high porosity of the coating.
摘要本研究分析了电解质成分对EV31镁合金等离子体电解氧化(PEO)涂层耐蚀性的影响。将12 g/l的Na3PO4与不同浓度的KOH(1、2和4 g/l)混合制备电解质溶液。PEO涂层是在0.05 mA的直流电流下制备的。电流密度为cm-2，最大电压为630 V。在0.1 M NaCl中浸泡1小时后，采用电化学阻抗谱法测定其耐蚀性。结果表明，KOH含量对PEO涂层的形貌和耐蚀性有显著影响，这与以往的类似研究结果一致。电解液中KOH浓度为2 g/l时，PEO涂层的孔隙率最低，极化电阻最高，耐腐蚀性最佳。当电解液中KOH浓度为4 g/l时，Nyquist图中只出现一个电容回路，极化电阻Rp值较低，说明涂层孔隙率高，致密性不足。

Abstract. Hydraulic systems are widely spread among drive and control systems. They can play a crucial role in many applications; therefore, identifying potential failures and their causes might be required. Quality improvement tools and methods can be used to achieve this goal. This research attempts to apply one of the recently developed tools, which is a systematic diagram, to recognize possible failures and their causes and finally to define preventive measures for a typical hydraulic vane pump. The analysis of potential pump failures and their causes identified oil contamination as the primary source of pump failure or malfunction. Consequently, proper maintenance was found to be the proper preventive measure.

Abstract. In recent times, the importance of occupational health and safety has escalated for modern enterprises. This shift can be attributed to the emergence of the COVID-19 virus, which compelled numerous businesses to adopt crisis management strategies and embrace remote work arrangements. It can be argued that the pandemic necessitated employers to implement suitable health and safety measures in order to sustain their operations in the labor market. The objective of this study is to evaluate occupational risks, considering the implications arising from the pandemic, and subsequently assess the provision of safe and hygienic conditions during this period. It is important to note that workplace hygiene requirements can vary based on the company, industry, and job role. Different work environments will entail distinct hygiene demands, and certain occupations or industries may even entail additional risks warranting extra protection. Hence, the assessment focused solely on production positions such as machine operators, fitters, quality inspectors, and warehouse workers.
